Abstract

Three specimens of Bi₂(Sr_0.9La_0.1)₂Cu _1-xCo_xO_y, with x = 0.2, 0.6, 1.0, respectively, were investigated by transmission electron microscopy to explore the influences of Co substitution for Cu on the structural modulation. They have in common orthorhombic modulated structures. But the modulation periodicity decreases gradually with the increase of Co content. Its ratio to the corresponding lattice parameter of basic structure equals 4.28 for x = 0.2, 4.18 for x = 0.6 and 4.00 for x = 1.0. Consequently, the modulated structures of the former two phases are incommensurate, while it is commensurate for the last one. The stacking disorder due to the weak bonding connection between two adjacent Bi-O layers has been observed in the two incommensurate modulated phases.
